 DETAILED DESCRIPTION

Various embodiments of the disclosure are discussed in detail below. While specific implementations are discussed, it should be understood that this is done for illustration purposes only. A person skilled in the relevant art will recognize that other components and configurations may be used without parting from the spirit and scope of the disclosure.

FIG. 1 illustrates a tile replacement solar panel frame mounting system 100 including a mounting clamp assembly 110 coupled to a support arm assembly 120 that is thread on to a post 130 secured to an installation surface through a tile replacement flashing 140. Mounting clamp assembly 110 includes a top clamp 150, a bottom clamp 152, and a fastener 154 that is inserted through the top clamp 150 and the bottom clamp 152, and fastened with a fastener nut. Some embodiments of the present technology involve a base flashing and an attachment bracket that can be used to secure the post 130 to the installation surface.

FIG. 2A illustrates a base flashing 150 that can be used in the tile replacement solar panel frame mounting system 100. The base flashing 150 can be installed on an installation surface 152 and can be configured to act as a barrier to water reaching holes in installation surface created through installing the tile replacement solar panel frame mounting system 100. In some cases, the installation surface 152 can be covered with a moisture barrier, vapor barrier, etc. and a portion of the base flashing 150 can slide under the barrier.

The base flashing 150 can include through-holes 154 for allowing fasteners to traverse the base flashing 150 and to be fastened to the installation surface. Also, the through-holes 154 can be sized to allow the base flashing a degree of movement about a fastener until the fastener is tightly secured to the installation surface 152.

The base flashing 150 can include a ridge feature 156 that extends across the base flashing 150. The ridge feature 156 can be used to inhibit water from flowing into the region of the base flashing 150 containing the through-holes 154. For example, when an installation surface is sloped, the base flashing 150 can be positioned with the ridge feature 156 up-slope from the through-holes 154. In this configuration, water flowing down-slope on the installation surface is inhibited by the ridge feature 156 and prevented from reaching the through-holes 154. In some cases, the surfaces of the ridge feature 156 are configured at angles that allow the base flashing 150 to stack on a like base flashing 150. Also, in some cases, the ridge feature 156 has a geometry that prevents water from pooling along its surface. For example, FIG. 2B illustrates a top view of a base flashing 150 with a chevron-shaped ridge feature 156 and FIG. 2C illustrates a top view of a base flashing 150 with a curved ridge feature 157.

The tile replacement solar panel frame mounting system 100 can also include an attachment bracket that supports the post 130. FIG. 3A illustrates an attachment bracket 160. The attachment bracket 160 includes a raised center section 162 and two flat sections 164, 166 that interface with the base flashing 150 or directly with an installation surface. In some cases, the flat sections 164, 166 include a plurality of attachment slots 168 along the length of the attachment bracket 160. The attachment slots are configured to receive a fastener for coupling the attachment bracket 160 to the installation surface.

The attachment bracket 160 also includes a post slot 169 in the raised center section 162. The post slot 169 can be configured to accept a coupling feature of a post, e.g. a T-bolt, cam fastener, etc. (explained in greater detail below). The post slot 169 can have an extended length (i.e. along the x-axis) to allow the post to be coupled in a variety of positions within the post slot 169. Also, the multiple attachment slots 168 allow the attachment bracket 160 to be fastened in a variety of positions relative to a roof joist, stud, etc. Additionally, the raised center section 162 can be truncated to occupy only a portion of the length (i.e. along the x-axis) of the attachment bracket 160—leaving a gap 163 or a flat center portion (not shown). The gap 163 or flat center portion defined by the truncated raised center section 162 can accommodate the attachment bracket 160 being partially positioned under an adjacent tile.

The multiple attachment slots 168 can also extend along a width (i.e. the y-axis) of the flat sections 164, 166 to allow the attachment bracket 160 to be adjusted up and down on an installation surface. The attachment slots 168 can be sized to allow the attachment bracket 160 a degree of movement about one or more fasteners until the fastener(s) is tightly secured to the installation surface 152. Furthermore, the extended post slot 169 and the multiple attachment slots 168 allow the attachment bracket to be fastened to a roof joist, etc., in a variety of positions while the post 130 remains in the same position relative to the installation surface and tiles. Moreover, the adjustability provided by the extended post slot 169, the multiple attachment slots 168, the extended width of the attachment slots 168, and the truncated raised center section 162 provide synergistic adjustment effects in both the x-axis and y-axis directions. The extended post slot 169 may provide additional x-axis flexibility to position the post 130 after the attachment bracket 160 has already been secured to installation surface 152. In some cases, the attachment bracket 160 can be formed of a single piece of sheet metal. Also, the attachment bracket 160 can be formed without having any orthogonal features, thereby allowing multiple attachment brackets to be stackable with one another.

FIG. 3B illustrates an attachment bracket 160 fastened to an installation surface 152 over a base flashing 150. The installation surface 152 is exposed after removing two tiles 102, 104 (illustrated using dashed lines). As shown, the gap 163 or flat center portion defined by the truncated raised center section 162 allows the attachment bracket 160 to fit under tile 104. Therefore, installation of the attachment bracket 160 can be achieved by removing only tile 102, and attachment bracket 160 can be fastened to a structural rafter under roof tile 104 without interference with roof tile 104. After the attachment bracket 160 is fastened to the installation surface 152, a tile replacement flashing 140 can be coupled with adjacent tiles, and may take the place of roof tile 102.

FIG. 4A illustrates the tile replacement solar panel frame mounting system 100 with a tile replacement flashing 140 installed over the base flashing 150 and the attachment bracket 160. In the some embodiments, the tile replacement flashing 140 includes a substantially planar surface 142 and a conical protrusion 144 having an aperture 146 disposed therethrough. The conical protrusion 144 prevents water running over the tile replacement flashing 140 from entering the aperture 146. The aperture 146 can be configured to receive the post 130. In some cases, the dimensions of the aperture 146 are slightly larger than the dimensions of the post 130 to facilitate installation of the post 130 through the aperture 146 and to allow the post 130 to couple with the attachment bracket 160 (as shown in more detail below).

The conical protrusion 144 can be configured with an angle of protrusion from the plane of the tile replacement flashing 140 that is selected for one or more design objective. For example, the conical protrusion 144 can be non-orthogonal to the plane of the tile replacement flashing 140. In these cases, the conical protrusion 144 is configured with angle of protrusion from the plane of the tile replacement flashing 140 that accounts for an angle of a roof such that the post is perpendicular to the installation surface 152 when installed within the tile replacement solar panel frame mounting system 100. The tile replacement flashing 140 can also include a chamfer 148 on a corner of the top surface to facilitate easier manufacturing of the tile replacement flashing 140. In the embodiment shown, the chamfer 148 reduces the drawing required of the metal on the corner of the tile replacement flashing 140 where it interlocks with adjacent roof tile and forms down to meet the roof tile below.

Some embodiments of the present invention involve a tile replacement flashing with upward and/or downward protruding stiffening ribs formed into its planar surface. FIG. 4B-4C illustrates a tile replacement flashing 140′ with stiffening ribs 143a-143d formed into its planar surface 142′. The stiffening ribs 143a-143d serve to ensure the planar surface 142′ remains substantially planar during the manufacturing process. Stiffening ribs 143a-143d can also provide structural rigidity to help maintain a flat profile of tile replacement flashing 140′ during its installation on a tile roof. Stiffening ribs 143a-143d may be angled relative to the x-axis in order to allow water to flow off tile replacement flashing 140′ and not pool. Stiffening ribs 143a-143d that are protruding downward towards the installation surface may also have an angled protrusion profile relative to the Z-axis allow water to drain out. Stiffening ribs 143a-143d may also have a protrusion profile with drafted sides to allow for stackability of multiple tile replacement flashings 140′. Tile replacement flashing 140′ includes a top surface 401, and a side surface 403. The top surface 401 and the side surface 403 define a cavity 405 beneath the top surface.

FIG. 5A illustrates the post 130 according to some embodiments of the present technology. The post 130 can be a substantially axial member with a threaded section 132 on a first terminal end, a non-threaded extender section 134, and a coupling mechanism 136 on a second terminal end. The threaded section 132 can be configured to thread into the internal threading of a support arm assembly 120 or extender arm (as explained below). The non-threaded extender section 134 can be configured to traverse the aperture 146 in the conical protrusion 144 of the tile replacement flashing 140 to allow the coupling mechanism 136 to couple with the attachment bracket 160. Also, the non-threaded extender section 134 extends away from the installation surface such that a component threaded onto the threaded section 132 can be adjusted to various heights relative to the installation surface without requiring adjustment to the post 130 or attachment bracket 160. The post 130 can also have an internal threaded section on a first terminal end to allow for attachment of other brackets. In this case, the post 130 may not have an external threaded section 132, as shown in FIG. 5C. Instead, the post 130 can have an internal threading section 138 to attach other components, such as an L-Foot.

Additionally, the post 130 can have a length to accommodate roofing tiles having a wide range of thicknesses and types (e.g. flat roofing tiles, S-type roofing tiles, ridge-type roofing tiles, Spanish-type roofing tiles, etc.). In some embodiments, post 130 may have all or a portion 139 of its body truncated to allow for a wrench to easily grip and rotate said post 130, as shown in FIG. 5D.

Also, the aperture 146 of the conical protrusion 144 of the tile replacement flashing 140 can be configured to allow the coupling mechanism 136 of the post 130 to be coupled with the attachment bracket 160 before or after the tile replacement flashing 140 is installed over the attachment bracket 160. This allows an installer to be able to install the tile replacement solar panel frame mounting system 100 without having to lift adjacent tiles when sliding in the tile replacement flashing 140.

In some cases, the attachment bracket 160 can be coupled with the post 130 and the tile replacement flashing 140 can be placed over the post 130 before fastening the attachment bracket 160 to the installation surface 152. The tile replacement flashing 140 can be removed to expose an area over the installation surface where the post can be located when the tile replacement flashing is finally installed. Next, the attachment bracket 160 can be adjusted (e.g. by selecting the appropriate attachment slots 168) to allow the post to be positioned within the appropriate area and to allow attachment slots 168 to align with a joist, stud, etc.

FIG. 5B illustrates the post 130 coupled with the attachment bracket 160 according to some embodiments of the present technology. In FIG. 5B the coupling mechanism 136 is a T-bolt coupling that fits into the post slot 169 of the attachment bracket 160. The T-bolt type coupling mechanism 136 is positioned through the post slot 169 and then post 130 can be twisted to engage the T-bolt type coupling mechanism 136 with the sides of the attachment bracket 160 to secure the post 130 within the attachment bracket 160. The T-bolt type coupling mechanism interferes with the sides of the attachment bracket 160 when the post 130 is rotated, thereby engaging the threads of the T-bolt type coupling mechanism to compress the post 130 against the attachment bracket 130. In some cases, the coupling mechanism 136 is a cam type mechanism. In these cases, the cam type coupling mechanism 136 of the post 130 can be installed in the post slot 169 and turned (e.g. ninety degrees) to engage with the side walls of the attachment bracket and an internal mechanism in the post would draw the post 130 against the attachment bracket 160. In either case, the post 130 can be pre-assembled with the t-bolt type coupling mechanism 136 or cam type mechanism to allow for reduced installation time on the rooftop.

FIGS. 6A-6B illustrate a tile replacement solar panel frame mounting system 100 with a post 130 installed through a tile replacement flashing 140 into an attachment bracket (not shown). As shown in FIG. 6B, a rubber boot 122 can be installed over the post 130 and on to the conical protrusion 144 to seal the conical protrusion 144. Next, a support arm assembly 120 can be thread onto the threaded section 132 of the post 130 and the mounting clamp assembly 110 can be fastened to the support arm assembly 120. The length of the threaded section (not shown) allows the support arm assembly 120 and the mounting clamp assembly 110 to be vertically adjustable. Also, each of the support arm assembly 120 and the mounting clamp assembly 110 can include slots for allowing the mounting clamp assembly to be adjustable in a plane of the installation surface. When multiple support arm assemblies 120 and multiple mounting clamp assemblies 110 are installed in an array, the vertical and planar adjustability offers installers a wide degree of flexibility and misalignment correction caused by undulations in the installation surface and human error.

FIG. 6C illustrates a tile replacement solar panel frame mounting system 100 with a post 130 having an internal threading section 138 and installed through a tile replacement flashing 140.

FIGS. 7A-7B illustrate an extender arm 170 that is configured to couple with the post 130 and that includes an internal section 178, a sloping extension section 172 and an extender post 174. The sloping of the sloping extension section 172 and the height of the extender post 174 can be configured to place a threaded portion 176 of the extender post 176 at substantially the same height (701) of the threaded section 132 of the post 130 relative to the installation surface. The extender post 170 allows additional adjustability when an edge of a module (e.g. a solar PV module) does not come within the range of the support arm assembly 120. In some embodiments, the post 130 can be configured with an extended S-shape to act as the post 130/extender arm 170 combination.

FIG. 8 illustrates a tile replacement solar panel frame mounting system 100′ according to some embodiments of the present technology. The tile replacement solar panel frame mounting system 100′ can include an S-type tile replacement flashing 140′ and universal components: a mounting clamp assembly 110, a support arm assembly 120, a post 130, a coupling mechanism (not shown), a base flashing (not shown), an attachment bracket (not shown).

The various embodiments described above are provided by way of illustration only and should not be construed to limit the scope of the disclosure. Those skilled in the art will readily recognize various modifications and changes that may be made to the principles described herein without following the example embodiments and applications illustrated and described herein, and without departing from the spirit and scope of the disclosure.
